Besides the average thickness of 10#coal seam is nearly 4m. The designed mine resource is 106.6 Mt and recoverable reserves is 90.56 Mt.The coal seam of design production capacity is 1.8Mt/a and the length of service is 50.2 years.This mine uses shaft development way, sets the main shaft, auxiliary shaft and air shaft.According to relevant state laws and regulations, Industry standard and Basic data Provide by Milky Way Coal Mine, the design put forward 2 technically feasible, economically reasonable mine development scheme. After the comparison, scheme 1 is seleted. That is adit opening in two level, panel strip retreating working, long wall fully mechanized mining overall height in one times. ，Designed first mining district, the length of working face is 200 m, which uses fully-mechanized coal mining technology, and fully caving method to deal with goaf. The working system is “three-eight”,with two teams mining, and the other overhauling. Every mining team makes three working cycle, with4working cycle everyday. Advance of working cycle is 0.8 m, In the initial stage, the mine apply centralized and exhaust ventilation, and partition type ventilation in later stage.
